| dc.description | A series of samples of Zn-22 wt.% Al alloy with different fine grain sizes are studied using Doppler broadening and lifetime spectra of positron annihilation. It is reasonable to assume that the lifetime of positron trapping at the grain boundaries is about 240 ps. The relationship between the mean positron lifetime and the inverse grain size is linear only when the grain size is larger than 0.5 mu m. |
